Analysis of the Intermediate-State Contributions to Neutrinoless Double β⁻ Decays

Figure 5

Multipole decompositions for the ground-state-to-ground-state decay of the nucleus ⁷⁶Ge ((a) and (b) panels) and for the ground-state-to-excited-state decay of the nucleus ⁸²Se ((c) and (d) panels). The value was used for (a) and (c) panels and the value for (b) and (d) panels.

(a) ⁷⁶Ge()

(b) ⁷⁶Ge()

(c) ⁸²Se()

(d) ⁸²Se()
